FOLDER FOR SEWING MCA(LHINES.` -Application led Octoberil, 1922.' Serial No. 598,074.

To all ictpmtz'z? may concern Be it -known that I,

of Illinois, have invented certain new and useful Improvements in Folders'tor Sewing Machinesof which the following is a specification, reference being had therein `to the accompanying drawings.

This invention relates to strip-guides and, more particularly', to strip-folding guides or binders for sewing machines. The invention l has foran object to provide a strip-guide and, more particularly, a binder which will satisfactorily -handle coated materials or fabrics, such as pantasote, customarily used in the manufacture of automobile tops.' Another object of the invention is to provide a folding .attachment forl sewing machines which will satisfactorily handle pantasote or similar coated materials.

To these ends, the attachment havinga guiding passageway is provided adjacent its ,i receiving end with a lubricantI receptacle having an opening adjacent and in communication with the, guiding passageway. Lu

bricant from the receptacle is applied to the coated side of the work means oit a wiper during the passage of the work through the attachment. Preferably the lubricant receptacle is filled with au oil vsaturated packing which protrudeg through a slot formed in the side wall of such receptacle and wipes over the coated faceof the material` thus depositing thereon a film of oil serving to prevent sticking or excessive drag of the material iii-the attachment. l

In the accompanying drawings. Fig. 1 is a perspective view of a sewing machinev attachment embodying the'invention. Fig. 2 isa perspective view of the attachment from another view-point showing the lubricant receptacle. Fig. 3 is a horizontal section through the receiving end of the attachment. Fig. 4 is a vertical section through vthe delivery end of thc attachment. Fig. 5

is a vertical section t-hroughthe device adjacent its receiving end, and Fig. 6 is a section through the seam produced by the attachment.

In .the specific embodiment of the invention chosen for the purpose of the present disclosure 1 represents thel body ,of a strip-- iolder in the form of a binder adapted to fold in the raw edges of a strip of material and apply the folded strip as abinding to CARLOS RAcNvnLD Ross, a citizen of the United States, residing.4 at Chicago, inthecounty of Cook and Statethe raw edge ofa body-fabric. Projecting laterally from the binder body` l is the usual horizontal shank 2 which is slotted at 3 for reception of the fastening screws 4 whereby the attachment may be 'secured to the bed 5 of a sewing machine. The sewing machine maybe of any usual type and may comprise Aa reciprocating eye-pointed needle 6 coope erating with a lower looptaker (not shown). The feed may include the usual alternating presser 7 and upper feed-foot 8 adaptedfto cooperate with the usual lower feed-dog (not shown) jend is substantially vertical in cross section as shownin Fig. and'progressively merges linto a U-form toward its delivery end; folding wings or scrolls 10 and tongues 10 being provided to fold in the raw edges of the binding` strip in the usual manner.

Secured to or formed integral with the attachment body 1 is the lubricant receptacle 11 which is stationed adjacent the receiving end of the passageway 9 and is preferably oit cylindrical form, being disposed with its axis substantially vertical and its outer wall substantially continuous with the inner guidingwall 12 of the attachment. The lubricant Yreceptacle 11 is. closed at its ends by means of the lateral ears 13. 14; the latter having an opening 15 through which the lubricant may be applied to an absorbent In order to provide for the application of the lubricant in the receptacle 11 to the coated side ot a strip passing through the attachment. th'e cylindrical wall ot the receptacle is formed with an opening or slot 17 through which projects a tongue 18 of the packing 16; said tongiie being adapted to wipe over the c oated surface 19 ot the binding strip 20. A guide-wall 21, connected at its opposite ends to the ears 13, 14 and opposed to the tongue 17, insures contact of the strip 20 with-such tongue. The attachmentmay he formed with a work-supporti@ for the body-fabric to be bound and an edge-guide `2% to guide theedge of the assembled Work a fixed distance at one side of the needle. The ears 13, 14: act as edge-guides for the strip 20 at the receiving end of the attachment and insure an application of lubricant across substantially the entire width of the strip 2O.v

Of course the space between the guard 2l and the receptacle 11 is, to all intents and purposes, a continuation or part of the passageway 9. So far as .I am aware, it is broadly new to provide a sewing machinev work-guiding` attachment of the type customarily stationed in advance of the presserfoot with a lubricating device adapted to facilitate the passage of the work therei Having thus set forththenature ofthe lnvention, what I claim-herein is I 1. A" folding vattachment for sewing inachin'es having a guiding passageway and a "-.passagewa'y for the. work, and a lubricant' applying device disposed at the receivingy end of said passageway. 25

lubricant receptacle. in communication with said passageway.

2. A folding attachment for sewing machines having a yfolder body formed with a 3. A folding attachment for sewing mav-chineshaving'a folder body formed with a body.

passageway for the work, and a lubricantapplying device carried by said folder body lat the receiving end of said passageway.

4. A folding attachment for `sewing mai chines having a folder body formed with a,

passageway for the work, a lubricant applying device carried by said folder body at the receiving end of saidpassageway, and an attaching shank secured to the folder` 5. A folding attachment for sewing machines having a folder body formed with apassageway and one or more folding scrolls, and a lubricant receptacle carried by said folder body and in communication with said passagewi-i-yI in advance of said scroll or scrolls.

` `6. A folding attachment for sewing machines having a folder body formed with a work-guiding passageway and curved folding walls, and means o n said attachment in advance of said curved walls, for lubricating the work.

7. A folding attachment for sewing machines having a strip folding passageway, a lubricant receptacle in communication with saidpassageway, and a lubricant absorbent material disposed in said receptacle and having a -tongue projecting into said passa ewa'ly. Y

8. '-fov ding attachment for sewing machineshaving'a strip folding passageway,l

a lubricant receptacle in communication with said passageway,` a lubricant absorbent material disposed in said receptacle and having a tongue projecting .into said passage-way, and a guide-wall opposed to said tongue.

`9. A foldingi attachment fornsewing machines comprising a .folding scroll,- a lubricant receptacle disposed in advance of saidsscroll and formed with an opening, a lubricant absorbent material disposed 'in said receptacle and extending through said opening, and a guide lopposed to said opening.

l0.
